Title: Semiconductor for gas sensor and manufacture of semiconductor for gas sensor
Inventor: IWAMOTO OSAMU
IPC: G01N27/12
Filed: 1994-02-09
Abstract: PURPOSE:To improve sensitivity of an indium oxide semiconductor for various kinds of gases by adding aluminum into the indium oxide semiconductor. CONSTITUTION:For example, indium oxide, whose purity is 99.99%, is used as a basic sputtering target. Under the state, wherein several aluminum chips having the impurity of 99.99% are mounted on the target, sputtering is performed. The sputtering conditions at this time are set so that the frequency is 13.56MHz, the attained pressure (pressure before the introduction of sputtering gas) is 5 micro-torricellis, and argon is used as the sputtering gas and the pressure is 3 milli-torricellis. The sputtering power is about 200 watts, and the film-forming rate at this time becomes about 25 angstroms. When a semiconductor (indium oxide) thin film having the thickness of about 500 milli-angstrom is formed, the sensitivity is increased by about seven times.

Title: Snow deposit and ice detecting method
Inventor: MATSUZAWA HIROSHI
IPC: G01W1/00
Filed: 1978-02-14
Abstract: PURPOSE: To enable detection of ice forming condition, by setting a thermometer and hygrometer at the temperature and humidity under which overcooled water drops exist, and judging presence of snow deposit or ice when the measured temperature is below the set value and the measured humidity is above the set value.  
     CONSTITUTION: A temperature detector 1 detects the temperature and sends the temperature signal to a controller 2, which closes a switch 3 when the temperature is below the set value. A humidity detector 4 detects the humidity and sends the humidity signal to a controller 5, which closes a switch 6 when the humidity is above the set value. Only when both switches 3 and 6 are closed, a circuit 9 is closed, and power is supplied from a power source 8 into a heater 7. This circuit 9 is not closed when either switch 3 or 6 is closed. Since the ice forming condition is established only when both the temperature and humidity conditions are satisfied by measuring both, the ice forming condition may be securely detected before ice is formed on object. Hence, when it is applied to ice preventive device, ice forming  may be prevented with a minimum of energy required.

Title: Optical input signal interrupt detection circuit
Inventor: YAMADA YASUHIRO
IPC: H04B10/60
Filed: 1992-01-31
Abstract: PURPOSE:To detect optical input signal interruption with stable operation regardless of an optical input level by ORing a control voltage of an AGC amplifier circuit and a monitor voltage of a timing extract circuit. CONSTITUTION:When an optical input level is P1 or below a gain of an AGC amplifier circuit 4 is a maximum, a gain control circuit 5 is saturated, a gain control voltage is compared with a reference voltage Vref1 to detect an optical input interruption. On the other hand, when the optical input level is P2 or over and no signal component is in existence, since the circuit 4 is operated by the occurrence of shot noise, the circuit 4 judges normal input through the detection of a gain control voltage. However, since no clock component is in existence, the control voltage is compared with a reference voltage Vref2 to detect the optical input signal interruption. That is, the AGC gain control voltage is compared with the reference voltage Vref1 by a 1st comparator 8 to detect that the optical input level is smaller than the level P1. Furthermore, the clock component is compared with the reference voltage Vref2 by a 2nd comparator 10 to detect signal component interruption and outputs of both comparators are ORed.

Abstract: PURPOSE:To suppress the occurrence of choppy noise or the like accompanied with inversion by providing a special course, where the stop time of a motor is made longer or shorter than that of standard operation courses and the operation execution time is made longer, besides standard operation courses. CONSTITUTION:A standard course, an elaborate course, a weak course, and a long course are alternatively selected and designated by a course selecting switch 19. In the standard course, a motor 5 is driven forward for a prescribed driving time and is stopped for a stop time and is driven backward for the driving time and is stopped for the next stop time, and this operation is repeated. In the long course, the motor is driven forward for the same driving time as the standard course and is stopped for a stop time longer than that of the standard course and is driven backward for the driving time and is next stopped, and this operation is repeated. Since the stop time of the motor 5 in this case is longer than that of the standard course, the attenuation time is extended to suppress the occurrence of noise accompanied with choppy and splashing phenomena though water current formed by rotation is strong.
